Abstract

A pneumatic spring (18) for damping the relative motion between a vehicle seat (22) and a base (24) upon which the seat (22) is mounted utilizes a rolling lobe sleeve (72), a plug (74) secured within one end of the sleeve (72) and a piston (70) secured within the other end of the sleeve (72) for movement toward and away from the plug (74) as the sleeve (72) rolls along the outside surface of the piston (70). The piston (70), sleeve (72) and plug (74) provide the surfaces of a variable-volume chamber (108) and the piston (70) includes an internal piston cavity (92) of a fixed size and shape. The variable-volume chamber (108) and piston cavity (92) contain a pneumatic fluid, and an orifice (110) is provided within the piston (70) which permits flow communication between the variable-volume chamber (108) and the piston cavity (92). <IMAGE>
